.To LU whom it rnalyleoncern: l

Be it known that I, DAVID CYNRIG Thomas, hoistin engin is a specification.

This 'invention relates to im rovements in I tires; and its object is vto provi e a tirehaving great resilience without the necessity of 'ja pneumatic tube with its attendantidisadvantages.

rubber or ot er resilient material, w ich sup-I ports the tire or forms the tire itself, is profvided with a `series of grooves crossing one another in such a manner that one or both faces of the strip are divided up vso as to'lea've a number of projecting studs separated by the grooves.

In order that my invention may be more clearly understood, I will 'describe it with reference to the accompanying drawings."

gitudinal and transverse rooves maybe made ob iquely, as shown at Figure 1 is a section of part of a Wheell'witli the ltire supported by a ring constructed accordance With this invention. Fig. 2 is a planof part of the ring shown in F' 1. 2 Fig.

In Fig. 1, ais the rim of the wheel. b is the ring'or inner tire, formed of india-rubber or' other resilient material.- In the inner and outer facesl ot the ring b are longitudinal and transverse grooves c-d, leaving the isolated' projections e,^as s'hoWn in Fig. 2. f ls Athe outer tire, which may be formed o'f solid rub- Iber or of metal brother suitable, substance.

In a wheel, the combination with -av rim, of a ring of resilient material lying in the rim arid'provided on both faces with lon itudinal `and transverse Grooves of substantially the 'same depth andying in the same plane, and 'an outer tire surrounding the ring, substantially as described.
